Abstract

With the popularity of cloud storage, its reliability and access latency have become increasingly prominent. To solve this problem, a novel strategy of dynamic replica creation based on acceleration is presented for cloud storage by drawing lessons from the concept of acceleration. For reducing access latency, the strategy predicts the hot files in the way of acceleration based on accessing locality principle. Finally, the performances of the strategy of acceleration replicas creation and the strategy of best client replicas creation are simulated and analyzed. The simulation results show that the strategy of acceleration replicas creation predicted hot files in the next period of time more accurately than the strategy of best client replicas creation, reduced network latency more than the strategy of best clients and the effect was being more pronounced with accessing trends rising. The strategy of acceleration replicas creation is suitable for cloud storage which is for handling massive files. By this strategy, not only the reliability of cloud storage data is improved, but also access latency is reduced.
